Quick Answer: What Is A Flask In Science?

What is flask in chemistry?

Flasks are useful types of chemistry glassware for containing liquid and performing mixing, heating, cooling, precipitation, condensation, and other processes. These flasks –also known as a science flask, chemistry flask, or a laboratory flask (lab flask)– come in a range of sizes, materials, and uses.

How do you use a science flask?

How to use a volumetric flask

  1. Add your solute to your solution.
  2. Add enough solvent to dissolve the solute.
  3. Keep adding your solvent until it gets close to the line marked on the volumetric flask.
  4. Use a pipette to fill the flask.

What is the difference between a beaker and a flask?

Flasks are notable for their unique shape: a rounded vessel and a cylindrical neck. The main differing characteristic between a flask and a beaker is that beakers have straight sides, rather than slanted sides like a flask. Beakers are mainly for measuring and transporting liquids from one site to the next.

What is a flask shape?

: resembling a typical flask in shape usually: necked and either globular or flattened in body.

What does a flask do?

Flask is a web framework. This means flask provides you with tools, libraries and technologies that allow you to build a web application. This web application can be some web pages, a blog, a wiki or go as big as a web-based calendar application or a commercial website.

What are the three types of flask?

The most common types of flask are:

  • Erlenmeyer flask.
  • Florence flask.
  • Volumetric flask.
  • Büchner flask.
  • Fernbach flask.

What is a flask used for alcohol?

Today, in a world in which every imaginable specialized beverage container is available, the flask is used primarily to carry one’s private supply of hard alcohol. It’s commonly given as a groomsman’s gift.

What is the purpose of a Erlenmeyer flask?

Erlenmeyer or titration flasks have wide flat bottoms, conical bodies, and tall cylindrical necks. They are named after their inventor Emil Erlenmeyer. Erlenmeyer flasks are used to contain liquids and for mixing, heating, cooling, incubation, filtration, storage, and other liquid-handling processes.

What is use of volumetric flask?

A volumetric flask is used when it is necessary to know both precisely and accurately the volume of the solution that is being prepared. Like volumetric pipets, volumetric flasks come in different sizes, depending on the volume of the solution being prepared.

Why use an Erlenmeyer flask instead of a beaker?

The Erlenmeyer flask offers a slight advantage in accuracy due to its tapered sides. The size of the beaker or flask should be chosen to allow for more liquid to be added during the titration process. This makes it simpler than subtracting once the titration is complete. There is a valve at the bottom of the burette.

What does a Erlenmeyer flask look like?

An Erlenmeyer flask, also known as a conical flask (British English) or a titration flask, is a type of laboratory flask which features a flat bottom, a conical body, and a cylindrical neck. Erlenmeyer flasks have wide bases, with sides that taper upward to a short vertical neck.

Is a flask more accurate than a beaker?

Graduated cylinders, beakers and Erlenmeyer flasks have less accuracy than volumetric glassware. Beakers and Erlenmeyer flasks should not be used to measure volume unless you need only a very crude estimate because their accuracy for volume measurements is so poor.

What is a round flask called?

The boiling flask, also known as a round bottom flask, is a chemical vessel with a spherical body and a cylindrical neck. It is most often used when heating solutions, particularly for distillation.

What is the use of Buchner flask?

Round-bottom flasks are used in distillation by chemists as distilling flasks and receiving flasks for the distillate (see distillation diagram). This flask shape is also more resistant to fracturing under vacuum, as a sphere more evenly distributes stress across its surface.
